When I pulled the sensor off for the 1st time I didn’t see a needle just a thread. Is there a needle injected or not?
No the needle goes in, inserts that thin wire then it’s pulled back out. The needle is only in you for a tenth of a second. If you look into the inserter after it’s used, you will see the needle still in there.
